Starting Feb 1, 2015, Apple is requiring all new app submissions to be 32/64-bit-universal. So between now and Jan 31, 2015, you can continue to submit your apps just as you do today, but once Feb 1 hits you’ll need to make sure certain changes are in place.

It appears Apple has been making changes a little too quickly lately. Their sudden changes to the app submission filters gave heartburn to many iOS developers, including yours truly. And then just today, they pulled iOS 8.0.1, their minor update to iOS 8, on the same day they released it.

Of course, Apple changed a number of things with iOS 8 that have affected iOS app development. We’ve been tracking these and wanted to give you a summary of the known issues in Corona and their status.

Starting in daily build 2014.2277, we are changing the minimum supported version on iOS from 5.1 to 6. This means that if you do a device build with 2014.2277 (or later), your app will not run on a device whose version is below iOS 6.

This change is needed to move our iOS architecture forward, and finally pay off technical debt that has been accumulating for nearly 18 months, which is an eternity in the mobile space.
